Translation, cultural adaptation and preliminary psychometric evaluation of the English version of “Strategy Inventory for Dictionary Use” (S.I.D.U)

Abstract

The present paper reports results regarding the adaptation in English of the Strategy Inventory for Dictionary Use (S.I.D.U.) and the preliminary psychometric evaluation of the English version. S.I.D.U is a 36-item self-report questionnaire for assessing dictionary use strategies specifying four main areas of interest: a) dictionary use awareness skills, b) strategies for dictionary selection and acquaintance with dictionary conventions, c) lemmatization strategies, and finally d) look-up strategies. The original scale was translated from Greek into English, back-translated and reviewed. Cross-cultural adaptation included the experts’ revision followed by its administration to 52 participants. Its internal consistency was .89. Similarly all four subscales showed good to excellent internal consistency (dictionary use awareness: α=.83, dictionary selection and acquaintance: α=.76, lemmatization: α=.86 and dictionary search: α=.78). Test-retest reliability ranged from fair to good for the total scale and its six-subscales
